A new acropomatid, Malakichthys barbatus, is described on the basis of 27 specimens (76.3–180.1 mm SL) collected from Suruga Bay to Tosa Bay, along the southern Pacific coast of Japan. The new species is unique in having numerous pairs of spines on the chin (a pair of spines in other congeners). Although the new species resembles M. elegans in having a slender body (the depth less than 35% SL), the former is further distinguishable from the latter in having a slender first proximal radial of the anal fin with no hollow (broad with a cone-shaped hollow in M. elegans), 43–48 lateral line scales (48–51), modally 21 gill rakers on the lower arm (modally 23), and a dark blotch on the opercle (no remarkable blotch).
